Is anyone here using Stiebel Eltron multi-point instance water heater?
Is it reliable and good?
Where can I go to have a look at some samples?

This one need very thick wiring. What model you looking at is it the 7kw heating element? That take minimal 30amps. Writing is crucial. If you are running on single phase you risk running your house electrical to the limit.

No problem with wiring because everything is still in design phase. It will be 3-phase.
I just need to know if the product is good or not? Or which model is good?

How much is it? A solar heater would be better?

I seen similar system during homedec, but no experience in it. Was part of my consideration when I renovate my house.

Any reason why you use this and not storage water heater or solar? You still need to use central piping.

storage water heater is a no no for me. consume a lot of electricity.
solar ... the problem with solar is that on rainy days when I need hot water, it 'doesn't work'. No sun. Need to use electric to heat up the water.
On normal days I dont shower with hot water.

Normal instant water heater like Joven etc are not nice ... I want something better. Stiebel Eltron seems perfect. It is safer also because you dont have to install the unit next to the shower. Plus I heard it is widely used in Germany. So, it cannot be that bad if it is a german product.

This unit still consume a lot of power. With 7kw of heating, that is 2x of instant water heater when run.

Your thinking of solar heater is wrong. The water is hot even in raining days. Microsolar efficiency is high even don't have heating element in their unit.

I am using storage water heater now.

Storage won't consume lots of electric, is only the initial warm up if you have not use it for few days or just install. Not sure from where you get the message that storage use more energy. It can even be much more efficient compare to instant.

Solar you want high efficient get micro solar.

Another one that is common use is rinnai gas water heater. Singapore and other country use it very frequent.

actually it is the same thing for storage vs stiebel. Storage heater consumes 3kW while stievel 7kW.

Assuming u r using a 25litres storage heater like JOVEN JH 25. U nd 2 wait 5 minutes for it to boil and you shower 10 minutes. (to make things simple, we assume kW consumption is per minute)

Total kW Consumed (Storage) = 15 x 3 = 45kW

Total kW Consumed (Stiebel) = 10 x 7 = 70kW

stiebel is a trusted brand from europe. cant go wrong there. but the right question has been asked WHY??

storage is cheaper
solar is cheaper

if you want instant - go for gas (way way cheaper). instant gas heaters work great, have almost zero maintenance and dont consume much gas. why burn gas first to make power, send to your place and then use it to heat up water? cut the middle man

thanks Zheilwane. I will validate the numbers (kW) and think again.

how is the maintenance of the solar panels? I heard we have to make sure it is clean in order to get the best performance?
any other maintenance?

All the arguments are valid. Last year i was building my house and was rally into solar, especially the microsolar water heater. Finally decided for steibel as the initial outlay was much less for 5 toilets, as i need hot water only for shower time, not the kitchen. Doing the maths, I wont use full hot water, just using the mixer to regulate the temperature of the shower and i dint spend much time there, maybe 2-3 minutes? All units are installed just above the ceiling and the copper piping is only 5 to 6 feet long.So far so good, instant hot water....maybe a 5 second lag.
Solar heaters need copper piping, thats costly if you wanna pipe the whole house and these are in wall pipes, you dont know when or where it can leak.
That my take, it really depends on what you require in your house.

"Stiebel Eltron"... hard to pronounce mia name... avoid

I am in agreement with you. When I take a shower, I just dont want the water to be cold ... that's all. In fact, I only turn on my hot water in the morning ... during rainy days. That's the reason why I was thinking of Stiebel Eltron. I also heard that it can be installed above ceiling.... which is something that I like.
Can you please share with me the model that you bought and the price, and also where you got them from? Please PM me if you dont want to share with others.

Hi TS, can I know at the end you installed Stiebel Eltron? How was it?

For multipoint instant water heaters in Malaysia ranged 5kW and above, from what I know, there is only a handful of choices:

1. BEEBEST | No longer in business.
2. STIEBEL ELTRON (Shopee / Lazada) | Expensive due to its German brand, nearly double the price compared to local brand.
3. CENTON (Shopee / Lazada) | From Shopee, looks like they have the most sales and positive reviews for multipoint instant water heaters. Locally manufactured, so no issue with getting it serviced.


Key point to note if you want to install multipoint instant water heaters like the ones above:

1. High electrical component and wiring spec requirements | Since their power ratings are much higher compared to common instant water heaters, your MCB, switch, wirings, all have to be higher in spec (refer to the Suruhanjaya Tenaga guideline table below), and can be expensive to replace / upgrade if you are currently under-spec'ed. For these water heaters that are above 5.711kW for example, u have to use 6mm electrical cables from the DB box to the water heater. Imagine all the wall hacking needed to replace the cables if it is currently under-spec'ed.

2. Isolation Barriers (protects u from current leakage) and Pressure Relief Valve (protects the internal tank from extreme high water pressure, which might lead to leaking / explosion) have to be installed at the water heater's inlet and outlet for your own safety, also stated in the Suruhanjaya Tenaga guideline. CENTON's multipoint instant water heaters have already been pre-installed with these safety parts.

3. Not suitable for bathtub / jacuzzi | No matter what the salesperson say, no instant water heaters in the market will be hot enough for bathtub or jacuzzi usage, and unless u are expecting to use just lukewarm temperature in your bathtub (and worst still during raining season where the inlet water temperature is much colder), u should opt for storage water heaters instead.

And contrary to believe that storage water heaters are energy guzzling appliances, storage water heaters' energy consumption are not significantly higher than multipoint instant water heaters since the hot water generated by the storage water heaters are also much higher compared to multipoint instant water heaters (laws of thermodynamics). Best-selling storage water heaters online are also from CENTON (Shopee / Lazada).
